get-function

Instructions

Implementation Reference

• src/index.ts:540-583 (handler)

  The handler function that implements the core logic of the 'get-function' tool. It retrieves detailed information about a specific function from Alibaba Cloud Function Compute (FC), including checks for custom domain configuration, using the FC SDK client.

  async (args) => {
      const { functionName, region } = args;
      const accessKeyId = process.env.ALIBABA_CLOUD_ACCESS_KEY_ID;
      const accessKeySecret = process.env.ALIBABA_CLOUD_ACCESS_KEY_SECRET;
      if (!accessKeyId || !accessKeySecret) {
          return { isError: true, content: [{ type: "text", text: `执行失败，请设置ALIBABA_CLOUD_ACCESS_KEY_ID, ALIBABA_CLOUD_ACCESS_KEY_SECRET, ALIBABA_CLOUD_SECURITY_TOKEN环境变量` }] };
      }
      const accountId = await getAccountId();
      if (!accountId) {
          return { isError: true, content: [{ type: "text", text: `执行失败，获取accountId异常` }] };
      }
      const fcClient = createFcClient(region);
      let getFunctionResult;
      try {
          const getFunctionRequest = new GetFunctionRequest({})
          getFunctionResult = await fcClient.getFunction(functionName, getFunctionRequest)
      } catch (error) {
          return { isError: true, content: [{ type: "text", text: `获取函数信息失败：${JSON.stringify(error as any)}` }] };
      }
  
      const functionInfo = {
          ...getFunctionResult.body,
      }
      const autoDomainName = getAutoCustomDomainName(accountId, functionName, region);
      let getCustomDomainResult;
      try {
          getCustomDomainResult = await fcClient.getCustomDomain(autoDomainName);
      } catch (error: any) {
          if (error.statusCode !== 404) {
              return { isError: true, content: [{ type: "text", text: `获取函数域名信息失败：${JSON.stringify(error as any)}` }] };
          }
          getCustomDomainResult = null;
      }
      if (getCustomDomainResult) {
          const routes = getCustomDomainResult.body?.routeConfig?.routes

              const route = routes[0];
              if (route.functionName == functionName) {
                  functionInfo.domain = autoDomainName;
              }
          }
      }
      return { content: [{ type: "text", text: `获取函数信息: ${JSON.stringify(functionInfo)}` }] };
  }

• src/index.ts:533-584 (registration)

      .describe("部署的区域，当前可选的区域是cn-hangzhou, cn-shanghai, cn-beijing, cn-shenzhen, cn-hongkong, ap-southeast-1, ap-southeast-2, ap-southeast-3, ap-southeast-5, ap-northeast-1, eu-central-1, eu-west-1, us-west-1, us-east-1, ap-south-1, me-east-1, cn-chengdu, cn-wulanchabu, cn-guangzhou，默认是cn-hangzhou");

• src/schema.ts:119-120 (schema)

  Zod schema definition for 'functionName' input parameter used in 'get-function' tool validation.

  export const functionNameSchema = z.string().describe("函数名称，函数名称在每个region必须是唯一的。")
      .regex(/^[a-zA-Z0-9_][a-zA-Z0-9_-]{0,63}$/);

• src/utils/alibaba_cloud_sdk.ts:11-17 (helper)

  Helper function to create an Alibaba Cloud FC client instance, used in the 'get-function' handler.
